[0027] like Figures 1 to 3 As shown, the movable positioning mechanism of the embodiment of the utility model comprises: a base 1, a positioning pin 2 and a driving mechanism 3.
[0028] Specifically, Figures 1 to 3 As shown, in this embodiment, the locating pin 2 is arranged on the base 1, and the base 1 provides a stable supporting platform to ensure the stability and reliability of the positioning mechanism, which is particularly important for applications that need to run for a long time or work in a vibration environment; the driving mechanism 3 is fixed on the base 1 and connected to the locating pin 2, driving the locating pin 2 to move along its length direction. Through the driving mechanism 3, the locating pin 2 can be automatically and flexibly positioned to adapt to different workpieces and facilitate the removal of the locating pin; the driving mechanism 3 can accurately control the movement of the locating pin 2 along its length direction, and can achieve fine-tuning and precision movement.
[0029] Further, if Figures 1 to 3 As shown, in this embodiment, it also includes: a guide sleeve 4, which is fixed on the base 1 and sleeved on the positioning pin 2. The guide sleeve 4 supports and guides the positioning pin 2, restricts the positioning pin 2, so that the positioning pin 2 can only move along its length direction, while ensuring the stability and precise guidance of the positioning pin 2.
[0030] Further, if Figures 1 to 3 As shown, in this embodiment, the driving mechanism 3 includes: a driving component, the driving component is fixed on the base 1; a rotating component, the rotating component is fixed on the base 1, one end of the rotating component is rotatably connected to the driving component, and the other end is rotatably connected to one end of the positioning pin 2; the driving component drives the rotating component to rotate, driving the positioning pin 2 to extend and retract along the guide sleeve 4; the movement range of the positioning pin 2 can be expanded, so that the dynamic positioning mechanism can adapt to a wider range of work requirements, and the points of action of the driving force and torque can be dispersed, reducing the stress concentration phenomenon that may be generated on the positioning pin 2, which helps to extend the service life of the positioning pin 2 and the mechanism, and reduce damage or destruction caused by stress concentration. At the same time, in a space with length restrictions, the setting of the rotating component enables the driving mechanism 3 to adapt to different space restrictions and improve applicability.

[0032] Further, if Figures 1 to 3 As shown, in this embodiment, the rotating assembly includes: a second mounting seat 33, the second mounting seat 33 is fixed on the base 1; a fixed shaft 34, the fixed shaft 34 is vertically mounted on the second mounting seat 33; a rotating sleeve 35, the rotating sleeve 35 is sleeved on the fixed shaft 34, the rotating sleeve 35 can rotate around the fixed shaft 34, and the rotating sleeve 35 is provided with two opposite side plates 36, and the two side plates 36 are respectively connected to the positioning pin 2 and the driving assembly. In this embodiment, the two side plates 36 are respectively connected to the positioning pin 2 and the driving assembly through the pin shaft 37 to achieve flexible rotation connection.
[0033] When in use, the output end of the cylinder 32 is extended and retracted, driving the rotating sleeve 35 to rotate, so that the side plate 36 and the positioning pin 2 connected to the side plate 36 rotate. Since the cylinder 32 and the first mounting seat 31 and the side plate 36, the positioning pin 2 and the side plate 36 are all hinged through the pin shaft 37, the positioning pin 2 is extended and retracted under the limit of the guide sleeve 4 to achieve the positioning of the workpiece.
